This chemical equation represents a synthesis reaction. This identification is based on the fact that the reactant chemical compounds combine to form a single chemical substance that is different from the initial chemical substance.

Setler [38]

The digeorge syndrome is a genetic disorder, which caused by the deletion in the chromosome number 22. This disease is characterized by the congenital heart disease, immunodeficiency, and hypocalcemia.

In this case, the most frequent clinical manifestation is hypocalcemia. Hypocalcemia is the condition, in which the blood calcium level would be declined to a significant level.

Barium metal has a body-centered cubic lattice with all atoms at lattice points; its density is 3.51 g/cm3. From these data and

stiks02 [169]

Answer:

The unit cell's edge length is $5.06\times 10^{-8} m$

Explanation:

Number of atom in BCC unit cell = Z = 2

Density of barium metal= $3.51g/cm^3$

Edge length of cubic unit cell= a = ?

Atomic mass of Ba(M) = 137.33 g/mol

Formula used :

$\rho=\frac{Z\times M}{N_{A}\times a^{3}}$

where,

= density

Z = number of atom in unit cell

M = atomic mass

$(N_{A})$ = Avogadro's number

a = edge length of unit cell

On substituting all the given values , we will get the value of 'a'.

$3.51 g/cm3=\frac{2\times 137.33g/mol}{6.022\times 10^{23} mol^{-1}\times (a)^{3}}$

$a = 5.06\times 10^{-8} m$

The unit cell's edge length is $5.06\times 10^{-8} m$

Makovka662 [10]

Answer:

After fertilization, a single cell divides successfully to form a multicellular structure. What happens next in order for this structure to develop tissues and organs to meet the needs of the organism? The cells undergo differentiation into particular body parts.

A multicellular organism develops from a single cell (the zygote) into a collection of many different cell types, organized into tissues and organs. Development involves cell division, body axis formation, tissue and organ development, and cell differentiation (gaining a final cell type identity).

Fuel cells are a particular type of electrochemical cell that require a constant source of chemical fuels, or reactants, during

bazaltina [42]

A fuel cell works like a battery. It consists of two electrodes where the reactions would occur and an electrolyte solution which allows for caharged particles to flow. In a fuel cell that uses hydrogen and oxygen as reactants. The hydrogen would enter the cell at the anode where oxidation would happen. So that the species that is formed in the anode side would be hydronium ions and electrons. The oxygen, on the other hand, would enter the cathode electrode where reduction occurs. The species that are produced in this side of the cell are water molecules. Together, the net reaction is called a redox reaction.
